In this study, we have proposed a new generalized estimator using auxiliary information for
the estimation of population variance in presence and absence of measurement error. The …

In this study, we have proposed memory-type ratio and product estimators for the estimation
of population variance based on exponentially weighted moving averages (EWMA) statistic …

The present study suggested memory-type ratio and product estimators for variance
estimation in the presence of measurement errors. We applied the exponentially weighted …

In this paper, we present an enhanced class of estimators for finite population variance
under simple random sampling that incorporates an auxiliary information. The equations for …

This study focuses on proposing the generalized exponential ratio-product estimator for
population variance in simple random sampling by using the combination of some existing …
